Reserve Your Seat TodayTo define PDU, we simply need to know what PDU stands for. A PDU, or Power Distribution Unit, is a device used in data centers to control and distribute electric power. For example, a power distribution unit rack mount setup is ideal for organized and efficient energy management in server environments. The most basic form of a PDU is a large power strip without surge protection. This is designed to provide standard electrical outlets for use within a variety of settings that don't require monitoring or remote access capabilities.
For larger projects, a floor-mounted PDU sometimes referred to as the Main Distribution Unit, provides a crucial management bridge that connects the building's primary power source and a variety of equipment racks within a data center or remote location. These units can handle considerably larger amounts of energy as well as the ability to support the load required by multiple racks of gear. When integrated with a power distribution unit rack mount, these systems ensure streamlined operations for multiple servers.
A rack-mounted PDU mounts directly into the equipment rack so it can monitor and control the power supply to specific servers, switches, and other data center devices and assist in balancing power loads. This makes a power distribution unit rack mount highly effective for space-saving installations and load management. These PDUs can be described by several different names including 'Smart' or Intelligent PDUs.
The acronym "PDU" stands for Power Distribution Unit. Basic PDUs are, essentially, industrial-grade power strips used (in most cases) to power servers and telecommunications equipment. Incorporating a power distribution unit rack mount adds further versatility for managing server-specific needs.
A basic PDU supplies power to server racks without advanced functionality. These are a low-cost server rack power distribution option.
You'll generally have too many devices at a site to plug them all directly into your power supply. You need PDUs to distribute your site's power to each device. This is possible because a PDU turns one (or a few) power inputs into many (usually about eight) power outputs. For data centers, a power distribution unit rack mount is critical for distributing energy efficiently across racks.
In other words, a power PDU is responsible for distributing reliable network power to your multiple devices. It can't generate power (so it's not a secondary power source), but it delivers AC or DC power from an uninterruptible power supply (UPS), a generator, or utility power to your remote equipment.
A power strip is a great example as a basic PDU, meaning it powers multiple devices using the current of a single power source, such as a wall outlet. Besides power distribution, modern PDU units can help you with equipment, environmental, and power monitoring.
Switched PDUs and metered PDU unyis are two of the most common types of power distribution units. Both types are often available in power distribution unit rack mount configurations, which make them suitable for scalable setups.
Metered PDUs provide network-grade power distribution. Switched PDUs also provide network-grade power distribution, but also remote monitoring and outlet control. Using a power distribution unit rack mount design for these PDUs enhances accessibility and ease of management.
Switched PDUs make it possible for you to remotely monitor and manage your outlets and other devices.
PDUs are available in both AC and DC models to match the power requirements at different kinds of sites. In most cases, an AC PDU will be powered with AC power and will distribute power with an alternating current. DC PDUs will sometimes differ in the sense that they all distribute DC power, but the PDU itself may be powered with AC or DC power, depending on the requirements of your site. When utilizing a power distribution unit rack mount design, compatibility with AC or DC power ensures smooth integration into any environment.
From a field tech's point of view, the units would function identically. DC units are built just like their AC counterparts, except for their output current.
DC power distribution units are designed to provide electric current in the direct current format that many rack-mounted devices use.
Now let's add another layer to our definition by adding the word "rack." A power distribution unit rack mount allows for efficient installation within industry-standard racks, ensuring compact and organized setups.
A basic "rack PDU" is a PDU that is designed to be mounted in an industry-standard equipment rack. These server racks are typically either 19 inches or 23 inches in width. Height can vary from PDU to PDU, but most are just one "rack unit" high. This translates to about 1.75 inches. The low profile of a power distribution unit rack mount saves space while delivering optimal performance.
A rack-mountable PDU is different from other kinds of PDUs that are designed to be wall-mounted or attached to the side of an equipment rack. These other PDUs conserve valuable physical rack space in cramped equipment racks, but they do increase the distance between the power outputs of the PDU and the power inputs of the devices that will receive electricity.
A rack-mounted power distribution unit usually can manage and distribute large amounts of electricity. They typically allow you to connect them to your current monitoring system and can be accessed remotely.
Basic PDUs are straightforward devices, primarily designed to distribute power without extra features. They often fall into two main categories:
Standard PDU: Functions as a power strip, providing multiple outlets for distributing electricity to connected devices. It doesn't offer any advanced monitoring or management capabilities.
Monitored PDU: While still fundamental in providing power distribution, this type includes basic electrical data displays. This allows for a minimal level of monitoring, showing current, voltage, or other essential metrics.
Intelligent power distribution units are an important part of an integrated monitoring system that protects mission-critical equipment. Using a power distribution unit rack mount for intelligent PDUs simplifies their installation and enhances accessibility for monitoring and control. An efficient unit will allow you to monitor and control the power at your individual outlets, switch power on or off, remotely shut down the power during an emergency power outage, and also allocate power efficiently.
Organizations rely on these PDUs not just for power distribution but to effectively monitor power efficiency and ensure consistent uptime. By using PDUs, businesses can gain insights into energy consumption patterns, allowing them to optimize usage and reduce waste, thus enhancing overall power efficiency.
Also, keep in mind that PDUs that were designed to meet your specific needs will be able to provide you with customized features to attend your remote sites' requirements.
In a nutshell, the most important advantages PDUs offer include:
To harness these benefits effectively, it's essential to understand the types of intelligent PDUs available and what features they offer:
Metered Inlet PDU: These units provide insights into power usage and available circuit capacity, facilitating efficient equipment provisioning and avoiding circuit overloads. They are instrumental in efficiency calculations.
Metered Outlet PDU: By metering at the outlet level, these PDUs help determine power usage and rack availability, allowing for comparisons to gauge the energy efficiency of devices.
Switched PDU: Offering all the functionalities of metered inlet PDUs, switched PDUs also allow for control over individual and groups of outlets, enabling remote power management and conservation.
Switched Rack PDU with Outlet Metering: Combining the features of both switched PDUs and outlet metering, these units provide comprehensive control and monitoring capabilities, ideal for sophisticated power management needs.
With an understanding of these types, you can choose the most suitable PDU for your infrastructure, ensuring your network components are not only protected but also optimized for energy efficiency and operational excellence.
